WARNING: This equipment generates, uses, and can radiate radio frequency

energy and if not installed and used in accordance with the instruction manual, may

cause interference to radio communications. It has been tested and found to comply

with the limits for class A computing device pursuant to Subpart B of Part 15 of FCC

Rules, which is designed to provide reasonable protection against such interference

when operated in a commercial environment. Operation of this equipment in a

residential area is likely to cause interference, in which case the user will be required

to correct the interference at his own expense.

Installation Precautions - Adherence to the following will aid in problem-free installation with long-term reliability:

WARNING - Several different sources of power can be connected to the fire alarm

control panel. Disconnect all sources of power before servicing. Control unit and

associated equipment may be damaged by removing and/or inserting cards,

modules, or interconnecting cables while the unit is energized. Do not attempt to

install, service, or operate this unit until this manual is read and understood.

CAUTION - System Reacceptance Test after Software Changes: To ensure

proper system operation, this product must be tested in accordance with NFPA 72-

1993 Chapter 7 after any programming operation or change in site-specific software.

Reacceptance testing is required after any change, addition or deletion of system

components, or after any modification, repair or adjustment to system hardware or

wiring.

All components, circuits, system operations, or software functions known to be

affected by a change must be 100% tested. In addition, to ensure that other

operations are not inadvertently affected, at least 10% of initiating devices that are

not directly affected by the change, up to a maximum of 50 devices, must also be

tested and proper system operation verified.

This system meets NFPA requirements for operation at 0-49O C/32-120O F

and at a relative humidity of 85% RH (non-condensing) at 30O C/86O F.

However, the useful life of the system's standby batteries and the electronic

components may be adversely affected by extreme temperature ranges and

humidity. Therefore, it is recommended that this system and its peripherals be

installed in an environment with a nominal room temperature of 15-27O C/60-80O

Verify that wire sizes are adequate for all initiating and indicating device loops.

Most devices cannot tolerate more than a 10% I.R. drop from the specified device

voltage.

Like all solid state electronic devices, this system may operate erratically or can

be damaged when subjected to lightning induced transients. Although no system is

completely immune from lightning transients and interferences, proper grounding will

reduce susceptibility. Overhead or outside aerial wiring is not recommended, due to

an increased susceptibility to nearby lightning strikes. Consult with the Technical

Services Department if any problems are anticipated or encountered.

Disconnect AC power and batteries prior to removing or inserting circuit boards.

Failure to do so can damage circuits.

Remove all electronic assemblies prior to any drilling, filing, reaming, or punching

of the enclosure. When possible, make all cable entries from the sides or rear.

Before making modifications, verify that they will not interfere with battery,

transformer, and printed circuit board location.

Do not tighten screw terminals more than 9 in-lbs. Over tightening may damage

threads, resulting in reduced terminal contact pressure and difficulty with screw

terminal removal.

This system contains static-sensitive components. Always ground yourself with a

proper wrist strap before handling any circuits so that static charges are removed

from the body. Use static suppressive packaging to protect electronic assemblies

removed from the unit.

Follow the instructions in the installation, operating, and programming manuals.

These instructions must be followed to avoid damage to the control panel and

associated equipment. FACP operation and reliability depend upon proper

installation.

Fire Alarm System Limitations

While installing a fire alarm system may make lower insurance

rates possible, it is not a substitute for fire insurance!

An automatic fire alarm system - typically made up of smoke detectors, heat

detectors, manual pull stations, audible warning devices, and a fire alarm control

with remote notification capability can provide early warning of a developing fire.

Such a system, however, does not assure protection against property damage or

loss of life resulting from a fire.

Any fire alarm system may fail for a variety of reasons:

Smoke detectors may not sense fire where smoke cannot reach the detectors such

as in chimneys, in walls, or roofs, or on the other side of closed doors. Smoke

detectors also may not sense a fire on another level or floor of a building. A second

floor detector, for example, may not sense a first floor or basement fire. Further-

more, all types of smoke detectors - both ionization and photoelectric types, have

sensing limitations. No type of smoke detector can sense every kind of fire caused

by carelessness and safety hazards like smoking in bed, violent explosions,

escaping gas, improper storage of flammable materials, overloaded electrical

circuits, children playing with matches, or arson.

IMPORTANT! Smoke detectors must be installed in the same room as the

control panel and in rooms used by the system for the connection of alarm

transmission wiring, communications, signaling, and/or power. If detectors are

not so located, a developing fire may damage the alarm system, crippling its

ability to report a fire.

Audible warning devices such as bells may not alert people if these devices are

located on the other side of closed or partly open doors or are located on another

floor of a building.

A fire alarm system will not operate without any electrical power. If AC power fails,

the system will operate from standby batteries only for a specified time.

Rate-of-Rise heat detectors may be subject to reduced sensitivity over time. For

this reason, the rate-of-rise feature of each detector should be tested at least once

per year by a qualified fire protection specialist.

Equipment used in the system may not be technically compatible with the control.

It is essential to use only equipment listed for service with your control panel.

Telephone lines needed to transmit alarm signals from a premise to a central

monitoring station may be out of service or temporarily disabled.

The most common cause of fire alarm malfunctions, however, is inadequate

maintenance. All devices and system wiring should be tested and maintained by

professional fire alarm installers following written procedures supplied with each

device. System inspection and testing should be scheduled monthly or as required

by National and/or local fire codes. Adequate written records of all inspections should

be kept.

Product Description

Document #50580 Rev.D 11/3/98 P/N 50580:D

CHAPTER 1 Product Description

The FIRE•COMMAND•25/50 Voice Evacuation Control Panel (VECP) is a single-channel, 25 watt, 25 VRMS, emer-

gency voice evacuation panel. The panel includes dual field programmable message capability (up to 60 seconds)

and an integral microphone. The base configuration requires that 24 VDC regulated power be provided to the

FIRE•COMMAND•25/50 for operational power. A separate custom power supply module with battery charger is

available and may be installed as an option to provide the 24 VDC regulated power. An optional second 25 watt

amplifier is also available for backup purposes or to provide an additional channel of 25 watts. Optional 70 VRMS

conversion modules are also available for installations where 70 VRMS speakers are to be installed or already exist.

The modular design allows for ease-of-serviceability.

Two Command Input Circuits can be independently field programmed for activation by an FACP Notification Appli-

ance Circuit reverse polarity or by closure of a supervised normally open contact. Terminals are provided for NAC

input and output to allow installation of the FIRE•COMMAND•25/50 anywhere along the NAC circuit being used to

activate it. Options via the Command Inputs allow one 60 second message over both amplifiers simultaneously or by

selecting amplifiers individually, two 30 second messages may be selected.

Significant technological enhancements set the FIRE•COMMAND•25/50 apart from other voice panels. These

enhancements include full supervision in both active (alarm or music) and standby conditions. Supervision is pro-

vided for:

✓amplifier outputs

✓field wiring (shorts and opens)

✓message generator

✓all tone generators

✓microphone

If the message generator fails, the system automatically reverts to the primary tone generator. If the primary tone

generator fails, one of three backups become enabled.

Power is fed independently to each amplifier so that a short circuit in one amplifier will not shut down the other. Full

output power of 25 watts per amplifier is generated while in a low battery condition. Power is not diminished when

the 70 VRMS option is installed. Audio is amplified from modern integrated circuits as opposed to transformer tech-

nology. This provides for very low signal distortion for crystal clear audio.

Primary applications for the FIRE•COMMAND•25/50 include nonhigh-rise structures such as restaurants, schools,

auditoriums, places of worship, buildings with occupancies over 50, etc. The FIRE•COMMAND•25/50 is designed

to interface directly to addressable or conventional fire alarm control panels or act as a complete stand-alone unit.

Input Circuits - CMD1 and CMD2

• The two input circuits are independently field programmable to accept Notification Appliance Circuits or nor-

mally open contacts. Terminals are provided to allow feed-through of the NACs, allowing placement of the

VECP anywhere along a Notification Appliance Circuit. A trouble on the VECP will cause relay contacts at

the out terminals of CMD1 to open, causing an NAC circuit trouble at the FACP. Note: The VECP will not

open the out terminals while in alarm. Monitoring VECP troubles while in alarm requires use of independent

trouble relay at TB1.

• Programming CMD1 and/or CMD2 for activation on contact closure will allow activation of the amplifiers on

a normally open contact transfer to the closed condition. Contact wiring is supervised for open conditions. A

short will cause amplifier activation (contact closure).

RCA Jack

• RCA Jack provides convenient connection to an audio source such as a tape player for recording a new digital

message. It may also be used for background music if approved by local AHJ.

Output Circuits

• Special Application Power Output, 35 mA @ 24 VDC.

• Optional Power Supply/Battery Charger FC-PSM(E) module provides power for the main circuit board in

standby and alarm at maximum power.

• The optional FC-PSM(E) module also provides a 24 Volt Battery Charger (up to 17 AH batteries) @ 800 mA

maximum.

Notification Appliance Circuit

• One NAC Speaker Circuit Style Y or Style Z with each FC-AAM25 amplifier module.

Relays

• One Form-C Trouble Relay. Contacts are rated 2.0 amps @ 30 VDC (resistive) and 0.6 amps @ 125 VAC

(resistive)

• When optional Power Supply/Battery Charger module is installed, one Form-C AC Loss relay is provided on

the module. Contacts are rated 2.0 amps @ 30 VDC (resistive) and 0.6 amps 125 VAC (resistive).

P1 and P5 Connectors (future use)

Local Speaker

• Connector P2 provides a connection for an optional, removable local speaker P/N: FC-LPS, to be used for

reviewing the digital message without broadcasting over the system speakers. Refer to Figure 3-18, “Installa-

tion of Speaker Module,” on page 31. This option module must be installed to take advantage of the Playback

feature. (The FC-LPS must be removed after use).

Components

1.5 Components

Main Circuit Board

The Master Unit main circuit board contains the

system's CPU, tone generators, auxiliary 35 mA

output, DIP switches for field programmable fea-

tures, digital message recorder/generator, inte-

gral microphone input and preamplifier, other

primary components and wiring interface com-

ponents. One amplifier module is supplied

mounted to the main circuit board. Optional

modules can be plugged in and mounted to the

main circuit board. The main circuit board is

delivered premounted in the cabinet.

Audio Amplifier Module (FC-AAM25)

A single Audio Amplifier Module is installed in the FIRE•COMMAND•25/50. The amplifier provides 25 watts

of power at 25 VRMS. An optional module, P/N: FC-XRM70, converts the 25 VRMS output to 70.7 VRMS. One

fully supervised and power-limited speaker circuit is provided on the amplifier module. The circuit can be wired

for Style Y (Class B) or Style Z (Class A) operation.

LEDs are provided to indicate Amplifier Supervision (green indicates amplifier is functional) and Circuit Trouble

(yellow indicates field wiring fault or amplifier fault). The LEDs are only visible with the panel door open.

Cabinet

The cabinet is red with an attractive navy blue front overlay. A clear window allows

viewing of status LEDs and location of microphone. The backbox measures 18.5" x

15.5" x 4.25" and provides space for two batteries (up to 7 Amp Hours).

Batteries

The cabinet provides space for 7 Amp Hour batteries (optional Power Supply/Battery

Charger module installation required). If larger than 7 Amp Hour batteries are to be

installed (17 AH maximum), use the Fire•Lite BB-17F battery box or similar UL listed

battery box. Batteries and BB-17F battery box must be ordered separately.

Dress Panel

The Dress Panel is supplied standard with the system. It mounts to the

cabinet with two supplied screws. The Dress Panel protects the user from

high voltages and circuit boards from accidental damage. All system

LEDs are visible with the Dress Panel installed.

1.6 Optional Modules

FC-AAM25 Audio Amplifier Module

An optional second identical audio amplifier can be plugged into connector P3 located in the lower center of the

main circuit board in the FIRE•COMMAND•25/50. This amplifier also provides 25 watts of power at 25 VRMS

and can therefore be used to expand system power to 50 watts (providing dual 25 watt speaker circuits) or it can be

used as a backup amplifier. An option module can also be used to convert the 25 VRMS output to 70.7 VRMS.

Note: For ease of access, all wiring should be connected to the terminals on the main circuit board terminal blocks

TB2, TB4, TB5 and TB6 prior to installing the secondary Audio Amplifier Module.

3.3 Operating Power

CAUTION: Several different sources of power can be connected to this panel. Disconnect all sources of power

before servicing. The panel and associated equipment may be damaged by removing and/or inserting cards, modules

or interconnecting cables while this unit is energized.

Main Input Power - Connections Made Only if Optional FC-PSM(E) Power Supply is Not Installed

The VECP requires filtered 24 VDC nominal power which can be supplied by a UL listed host FACP or a remote

power supply UL listed for Fire Protective Signaling Service, such as the FCPS-24F(E). Refer to Appendices for

wiring information. Supplied power must be from a power-limited source. Run a pair of wires from a regulated

24 VDC output on the host FACP or remote power supply to the VECP's TB3 Terminals 3(-) & 4(+). The jumper

on P7 pins 1 & 2 must remain installed. Be certain to connect a separate solid earth ground to the transformer

mounting stud to ensure proper panel operation and lightning and transient protection. Be certain to include the

FIRE•COMMAND•25/50 power requirements in the FACP or remote power supply battery calculations.

Internal Power Supply/Battery Charger FC-PSM(E)

An optional power supply is available to allow stand-alone capabilities and is required for background music

applications. AC power connections are made to the FC-PSM(E) Internal Power Supply/Battery Charger.

Primary power source is 120 VAC, 60 Hz, 1.0 amp for the FC-PSM Power Supply/Battery Charger module and

220/240 VAC, 50 Hz, 0.5 amps for the FC-PSME Power Supply/Battery Charger module. Run a pair of wires

(with ground conductor) from the protected premises main breaker box to TB1 of the FC-PSM(E). As per

National Electric Code, use 14 AWG (1.6 mm O.D.) or heavier gauge wire with 600V insulation. No other equip-

ment may be connected to this circuit. In addition, this circuit must be provided with overcurrent protection and

may not contain any power disconnect devices. A separate Earth Ground connection must be made to ensure

proper panel operation and lightning and transient protection. Connect the Earth Ground wire (minimum 14

AWG) to one of the transformer mounting studs. Do not use conduit for the Earth Ground connection since this

does not provide reliable protection.

CAUTION: When the FC-PSM(E) Power Supply/Battery Charger is installed, there should be no other connec-

tions to TB3 of the VECP.

Secondary Power Source (Batteries) When Power Supply/Battery Charger FC-PSM(E) is Installed

Observe polarity when connecting the battery. Connect the battery cable to P2 on the Internal Power Supply Bat-

tery Charger module using the plug-in connector and cable provided. The battery charger is current-limited and

capable of recharging sealed lead acid type batteries (See Figure 3-5 for battery orientation). The charger shuts

off when the system is in alarm. See Appendix A for calculation of the correct battery rating.

CAUTION: Battery contains sulfuric acid which can cause severe burns to the skin and eyes, and can destroy

fabrics. If contact is made with sulfuric acid, immediately flush the skin or eyes with water for 15 minutes and

seek immediate medical attention.

Auxiliary DC Power Output Connections

3.4 Auxiliary DC Power Output Connections

The Auxiliary DC power output is power-limited.

3.5 Input Circuits

The VECP has two Command Input circuits (CMD1 and CMD2), which are used to activate the panel amplifiers

which, in turn, transmit an audio signal over the system speakers. All field wiring for each circuit is power-limited

and supervised for opens and ground faults.

Each CMD Command Input circuit can be independently field programmed to be triggered by a contact closure or by

the reverse polarity of a Notification Appliance Circuit. CMD input and output terminals are provided to allow place-

ment of the VECP anywhere along a Notification Appliance Circuit allowing nondedicated use of host FACP NAC

for triggering. CMD1 has relay contacts (maximum current 2.0 amps) before the out terminals which will open the

outgoing NAC circuit during a VECP trouble condition. This causes an NAC trouble at the host FACP.

Note that the Command Input Circuit configurations can be independently set so that both circuits are triggered by

the same type of input or by different types of inputs (Refer to Figure 3-7 on page 23).

Master Command Output Bus

The Master Command Output is a 24 VDC reverse polarity output (TB6) which can be used to trigger additional

FIRE•COMMAND•25/50 units. The Master Command Output will activate on any alarm condition as triggered

by the Command Inputs CMD1 or CMD2, or when the manual evacuate switch is ON. It will not be active when

the Message Override switch is ON during general paging.

When connecting the Master Command Output of the main panel to the Command Inputs of other

FIRE•COMMAND•25/50 panels or to other devices, the wiring must be supervised by a 4.7K EOL resistor con-

nected across the out terminals of Command Input #1 on the last panel.

In Example 1 illustrated below, the audio output from each unit is not synchronized. Each VECP may generate a

different audio message if desired. Paging must be done at each individual panel's microphone.

The maximum line resistance from the main VECP to the last VECP is 130 ohms (65 ohms per conductor).

ferring its contacts.

AC Power Loss Relay - TB2

The optional FC-PSM(E) internal Power Supply/Battery Charger Module provides a Form-C AC Power Loss

relay rated for 2.0 amps @ 30 VDC (resistive) and 0.6 amps @ 125 VAC (resistive).

Notification Appliance Circuit (Speakers)

Each Amplifier Module provides one Notification Appliance Circuit for speakers. The circuit can be wired

Style Y (Class B) or Style Z (Class A). Each supervised and power-limited circuit is capable of 25 watts of power.

The maximum total capacitance for each speaker circuit cannot exceed 250 uF. Refer to the Fire•Lite Device

Compatibility Document for a listing of compatible speakers.

CAUTION: Match proper polarity connections to field wiring and speakers. Polarity shown is in the standby and

alarm conditions.

3.8 Installation of Option Modules

3.8.1 Audio Amplifier Module (FC-AAM25)

The optional audio amplifier module is identical to the module provided with the factory standard panel configura-

tion. It can be used to provide a second 25 watt speaker circuit, increasing the total VECP power to 50 watts, or it can

be used as a backup amplifier. LEDs on the amplifier module are for Amp Supervision (green - indicates amp func-

tional) and Circuit Trouble (yellow - indicates wiring fault or amplifier fail). Connector J1 of the audio amplifier

module plugs into connector P3 located at the bottom center of the main circuit board.

Caution: Before installing any modules, make certain all power (AC and DC) has been removed.

1. For ease of access, all wiring should be connected to the terminals on the main circuit board terminal blocks

TB2, TB4, TB5 and TB6 prior to installing the secondary Audio Amplifier Module.

2. Remove mounting screw shown, from the main circuit board, and save (refer to illustration below).

3. Install one supplied metal standoff in location from which mounting screw was removed in Step 2.

4. Install the Audio Amplifier Module by carefully aligning the amplifier's J1 connector with the P3 connector

CHAPTER 4 Operating Instructions

4.1 Switches

4.1.1 Manual Evacuate/Message Override

Manual Evacuate/Message Override is a two position switch used for

manually generating programmed evacuation tones/messages or for

paging. It is visible through the window of the closed backbox door.

The door must be unlocked and opened for access to the switch.

Switch activation will cause the following:

• Placing the switch in the UP or Manual Evacuate latching

position will generate the programmed evacuation tones/mes-

sages out of the amplifiers. Returning the switch to the nor-

mal position will stop the audio output.

• Holding the switch in the Down or Message Override non-

latching position interrupts the generated audio output from

the amplifiers if the unit is in alarm. This allows use of the

microphone for emergency paging. It is not necessary to hold

the switch down when paging while the system is in the

standby (nonalarm) state. Releasing the switch while in

alarm, returns the VECP to generating audio evacuation tone(s)/messages(s).

4.1.2 REC - Record Push Button

The switch labeled TROUBLE SILENCE is also used for recording a customized message. The switch is not labeled

as ‘record’ to help prevent unauthorized recording.

Recording Instructions

Recording a custom message or messages into the VECP requires that the voice message(s) be input via the

internal microphone or via the RCA Jack.

1. Select whether a single 60 second message or two 30 second messages will be recorded by setting S5 switch 2

to the OFF position for one 60 second message or to the ON position for two 30 second messages.

2. Enable recording by setting S5 switch 8 to the ON position. The Trouble Silence key is now ready to be used

in record operation.

3. Select the record input source by setting S5 switch 7 to the OFF position if recording via the microphone, or to

the ON position if recording via the RCA Jack.

4. Slide the Record Bypass switch S2 to the UP position to enable the message storage device.

5. Note the following while recording:

✓To alert the user that there is only five seconds of record time remaining, the REC LED will change

from steady-on to flashing

✓The system Trouble LED and Trouble Relay will be on while recording but the Trouble Sounder will

remain off. The system will not respond to the CMD inputs or Manual Evacuate switch while recording

✓It is not necessary to fill the entire 60 second or 30 second record time. The time limits represent the

maximum time allotted. For dual language recordings, it is recommended that the 60 second option be

selected. The two 30 second recordings should only be used for fire/nonfire or fire-evacuation/fire-clear

messages

✓Factory default messages are replaced with the custom messages recorded from the RCA jack or

internal microphone

CHAPTER 5 Application Examples

The FIRE•COMMAND•25/50 is a Voice Evacuation Control Panel which can be used, with a variety of Fire Alarm

Control Panels, to provide emergency audio messages. This chapter contains a few application examples and is not

meant to provide a comprehensive list of all possible VECP applications.

5.1 One Speaker Circuit

A very basic application consists of one FIRE•COMMAND•25/50 with one amplifier and a single speaker circuit.

This configuration is suitable for small facilities requiring no more than 25 watts of output power. A single fire evac-

uation message will be generated during an alarm condition from the host FACP or activation of the Manual Evacuate

switch.

In this application, the NAC from the host FACP is connected to CMD1. The CMD1 out terminals are then termi-

nated with an EOL resistor for the FACP's Style Y NAC or the terminals are wired back to the host FACP for a

Style Z NAC. S5 DIP switch 2 is set to OFF which causes the speaker circuit to be activated by the CMD1 input. S5

DIP switch 5 is set to OFF which causes CMD1 input to be activated by a reverse polarity condition.

One Speaker Circuit With Backup

5.2 One Speaker Circuit With Backup

Another application consists of one FIRE•COMMAND•25/50 with one amplifier and a single speaker circuit. A sec-

ond amplifier can be installed as a backup if desired. This configuration is suitable for small facilities requiring no

more than 25 watts of output power. A single 60 second fire evacuation message will be generated during an alarm

condition from the host FACP or activation of the Manual Evacuate switch.

In this application, the NAC from the host FACP is connected to CMD1. The CMD1 out terminals are then termi-

nated with an EOL resistor for the FACP's Style Y NAC or the terminals are wired back to the host FACP for a

Style Z NAC. S5 DIP switch 2 is set to OFF which causes the speaker circuit to be activated by the CMD1 input. S5

DIP switch 5 is set to OFF which causes CMD1 input to be activated by a reverse polarity condition.

Backup Amplifier switch S1 is set to the ‘Backup ON’ position. 18 AWG or larger jumpers connect the Backup

Amplifier TB2 Terminal 3 and Main Amplifier TB2 Terminal 2 as well as Backup Amplifier TB2 Terminal 4 and

Main Amplifier TB2 Terminal 1. Upon failure of the first or main amplifier, the audio from the backup amplifier will

be switched out to the speakers.

Note that in the optional 70.7 VRMS configuration, only the amplifier is backed-up; the FC-XRM70 coupling trans-

former is not. For this reason, it is not necessary to install an FC-XRM70 transformer module on the backup

amplifier.

Two Speaker Circuits - One 60 Second Message On Both Amps

Document #50580 Rev.D 11/3/98 P/N 50580:D

5.3 Two Speaker Circuits - One 60 Second Message On Both Amps

This application consists of one FIRE•COMMAND•25/50 with two speaker circuits which requires installation of the

optional second amplifier. This configuration is suitable for small facilities requiring no more than 50 watts of output

power. A 60 second fire evacuation message will be generated over both speaker circuits simultaneously during an

alarm condition from the host FACP or when the Manual Evacuate switch is activated.

In this application, the one NAC from the host FACP is connected to CMD1 In terminals. The CMD1 Out terminals

are then jumpered to the CMD2 In terminals. The CMD2 Out terminals may then be terminated with an EOL resistor

for the FACP's Style Y NAC or the terminals may be wired back to the host FACP for a Style Z NAC. Note that addi-

tional NAC devices may be connected to the CMD2 Out terminals as illustrated in Figure 5-3.

S5 DIP switch 2 is set to OFF which causes transmission of the primary ‘fire’ message over speaker circuits 1 and 2

upon activation of CMD1 and CMD2. S5 DIP switch 5 is set to OFF which causes CMD1 input to be activated by a

reverse polarity condition and S5 DIP switch 6 is set to OFF which also causes CMD2 input to be activated by a

reverse polarity condition.

Two Speaker Circuits - Two 30 Sec. Messages (Fire and Nonfire)

5.4 Two Speaker Circuits - Two 30 Sec. Messages (Fire and Nonfire)

This application consists of one FIRE•COMMAND•25/50 with two speaker circuits which requires installation of the

optional second amplifier. This configuration is suitable for small facilities requiring no more than 50 watts of total

output power (provided on dual 25 watt speaker circuits). A fire evacuation message will be generated over both

speaker circuits during an alarm condition from the host FACP and an emergency ‘nonfire’ message can be manually

generated over both circuits.

In this application, one NAC from the host FACP is connected to the CMD1 In terminals. The CMD1 Out terminals

are then terminated with an EOL resistor for the FACP's Style Y NAC or the terminals are wired back to the host

FACP for a Style Z NAC. CMD2 is connected to a normally open contact which can be used to manually generate an

emergency ‘nonfire’ message (i.e. tornado warning).

S5 DIP switch 2 is set to ON which causes transmission of the primary ‘fire’ message over speaker circuits 1 and 2

upon activation of CMD1 and transmission of the secondary ‘nonfire’ message over speaker circuits 1 and 2 upon

activation of CMD2. S5 DIP switch 5 is set to OFF which causes CMD1 input to be activated by a reverse polarity

condition and S5 DIP switch 6 is set to ON which causes CMD2 input to be activated by a contact closure.

Document #50580 Rev.D 11/3/98 P/N 50580:D

5.5 Two Speaker Circuits - One or Two Messages (CMD1 and CMD2

Amp Selection)

This application consists of one FIRE•COMMAND•25/50 with two speaker circuits which requires installation of the

optional second amplifier. This configuration is suitable for small facilities requiring no more than 50 watts of output

power. Depending on configuration switch settings and activation of one of the Command CMD inputs, a fire evacu-

ation message can be generated over one or both speaker circuits or one of two different messages can be generated

over both circuits.

In this application, one NAC from the host FACP is connected to CMD1. The CMD1 Out terminals are then termi-

nated with an EOL resistor for the FACP's Style Y NAC or the terminals are wired back to the host FACP for a

Style Z NAC. A second NAC from the host FACP is connected to CMD2. The CMD2 Out terminals are then termi-

nated with an EOL resistor for the FACP's Style Y NAC or the terminals are wired back to the host FACP for a

Style Z NAC.

S5 DIP switch 2 set to OFF causes transmission of one 60 second message. Activation of one or both CMD inputs

determine which amplifier is on. S5 DIP switch 2 set to ON causes transmission of two 30 second messages. Control

of which message to be played over both amplifiers is via CMD1 and CMD2 (refer to charts in Section 2.2). S5 DIP

switches 5 and 6 are set to OFF which causes CMD1 and CMD2 inputs to be activated by reverse polarity conditions.

Notes

Appendix D Addressable Module Connections

When configured with an addressable FACP such as the MS-9200(E), the FIRE•COMMAND•25/50 may be trig-

gered either by the FACP main NAC output or from addressable control modules. Figure D-1 illustrates CMD1 trig-

gered by an addressable control module. The addressable control module may trigger the FIRE•COMMAND•25/50

via reverse polarity (shown) or relay contact. The FACP monitors the FIRE•COMMAND•25/50 for faults while in

the standby or alarm state by wiring a monitor module to the trouble contacts as shown in Figure D-1. Activation of

the addressable control module is controlled by the FACP. Refer to the MS-9200(E) manual for additional

information.

Notes:

1. Auxiliary Power terminals for special application power only. Wiring must remain in the room.

2. Supervise the wiring between the FIRE•COMMAND•25/50 Auxiliary Power output and the control module

with an EOL relay (A77-716B)

3. EOL resistor supplied with modules.
